Description

Eli's suggestions for refactoring the three "wait for" loops in TestNodeCount for re-usability (similar to what was done for HDFS-1562): You could augment NameNodeAdapter#getReplicaInfo to return excess and live replica counts as well and then just add waitFor[Live|Excess]Replicas methods to DFSTestUtil and have TestNodeCount call them. This way we could re-use them in the other replication tests.
